Oh what a good thread, as I was looking to post a random thought and question myself but didnt want to open a new thread.

So there was only one helocopter on the boat, we know this because Naomi was shown arguing with Frank right before Frank and Mike's random conversation.

NAOMI: Sorry, Frank, but I'm going first and that's all there is to it.
FRANK: No offense, but I was flying these things when you were still in grade school. If anybody's gotta go first, it should be me.
NAOMI: I need you here to transport the science team.
FRANK: What the hell are you going to be doing?
NAOMI: That's need-to-know. You don't.

But then we saw in the near end of season 3 that Naomi parachuted (?) from a 'copter just before it crash landed in the ocean in the polar opposite area that she landed, almost as if she was rocketed out of it. So that would mean there were two helos, would it not? Just a bit confused about how Naomi came to be on the island in the first place. And why did she not have a gun?

Also, just a funny bit, Michael is the patron saint of parachuters!
